Abstract

Disclosed is an apparatus or device for making knots in a flexible element that engages a medical device, such as an IUD, and associated methods. The knot tying device receives the medical device in a loading element, and then threads the flexible member through an aperture of the medical device using a spooling element. A looping element and knotting element ties the flexible member into a knot. The devices, systems and methods can create a double loop surgeon's knot that are reproducible during the manufacturing process.
